Summary
This modelling study integrated economic, environmental and health data for Australia to estimate the co-benefits of incorporating greenhouse gas emissions pricing into food commodity prices. A carbon price of $23 per tonne CO2-equivalent embedded in food costs was projected to avoid approximately 49,500 DALYs through dietary shifts, reduce food-related emissions by 6%, and generate substantial public revenues. The analysis suggests that climate pricing mechanisms on food can simultaneously advance public health and emissions-reduction objectives.
UK applicability
The findings are relevant to UK policy discussions on carbon pricing and dietary change, though estimates would need recalibration for UK dietary patterns, food system structure, and emissions profiles. The methodology could inform UK public health and climate policy integration, though price elasticities and baseline consumption differ between the two countries.
Key measures
Avoided DALYs (49,500; 95% CI 43,200–55,200); food-related greenhouse gas emissions reduction (6%, 2.3 MtCO2-eq); tax revenues ($866 million); carbon price ($23 per tonne CO2-equivalent)
Outcomes reported
The study modelled the impacts of incorporating greenhouse gas emissions pricing (at $23 per tonne CO2-equivalent) into food commodity prices on dietary patterns, disease burden, emissions reductions, and public revenues in Australia. It measured avoided disability-adjusted life years (DALYs), reductions in food-related greenhouse gas emissions, and tax revenues generated.
